Tunable optical filter, active doped optical fibre with long period Bragg grating |
| 摘要 |
An optical transmission system includes a doped optical fibre 4, the dopant being capable of being excited by a source 6. The doped fibre includes a Bragg grating 5, the grating being a long period grating. The excitation source is coupled to the fibre by coupler 7. The coupler may be a WDM coupler. The Bragg grating in this case acts as a tunable optical filter.
